Abstract
The construction material mainly concrete is being used extensively for various types of construction projects. However, the deterioration of Reinforced Concrete structures is recognized as a major problem worldwide. Apart from requiring regular maintenance, many structures require extensive Repair/Rehabilitation/Retrofitting. Over a period of time, as these structures become older, we find in them certain degradation or deterioration with resultant distress manifested in the form of cracking, splitting, delaminating, corrosion etc. Such deteriorated structures can be rehabilitated and retrofitted by using various types of admixtures & modern repair materials. The paper brings out the present state of concrete structures & the major areas where improvement is needed during its service life stage for sustainable development & also the method of carrying out Repair/Rehabilitation/Retrofitting.This has been brought in details in the paper along with Case study, where the Author of the paper was directly involved in planning and execution of job.
Highlights
There is a growing National/International concern about the premature deterioration of our buildings/structures, concrete structures
The techniques and materials used for repair/rehabilitation/retrofitting and maintenance depend upon the extent of deterioration
Though polymers are in use in concrete for quite some time; they are known by the respective roles they play such as admixtures, bonding agents, sealants and so on
Summary
There is a growing National/International concern about the premature deterioration of our buildings/structures, concrete structures. This paper highlights the present state of maintenance especially in developing country like India and about the utilization of those new techniques/materials for repair/restoration of the buildings/structures, for long term sustainable development [1] It is a matter of serious concern of us the civil Engineers, that in some countries, the repair activities of structure done today account for nearly half the total annual expenditure on total construction activities [2]. This paper highlights the present state of maintenance especially in developing country like India and about the utilization of those new techniques/materials for repair/restoration of the buildings/structures, for long term sustainable development
